How can I get Python argparse parameters for a module as a string?

Question

I have a module that I'm writing an ipython notebook to document. I'd like to have part of that documentation be the response to calling the module from the command line with the --help flag - the parameters set up using argparse. Is there a simple way of getting that as a formatted string?

Call format_help() on your ArgumentParser instance. It will give you a string with the help text.

So what worked in the end is simply using subprocess.check_output as follows:

response = subprocess.check_output('python -m myscript -h')   
print response
